At this time, it is unclear what, if anything, is the issue. This may be as simple as the GREENAPPLE tool, which exploited the vulnerability found in MS05-011, being released in next month's CANVAS update. Or, this may be a new variant of the same. Or, this might be something entirely different.Or, this may be nothing at all.

Personally, I don't think there's anything to this other than what the message on DailyDave says: "Sinan Eren wrote a working version of GREENAPPLE, a remote kernel overflow in SMB for Windows 2000. It's available now to Immunity Partners, but it will be in the June Immunity CANVAS release, whichwill be interesting."
